The --empty-files-as-absent option was documented for lsdiff but not properly supported or documented for grepdiff. This option is useful with grepdiff -s/--status to correctly identify file additions vs modifications when files have empty old versions. For grepdiff, -E already means --extended-regexp, so the short form cannot be used. This commit makes --empty-files-as-absent available as a long option only for grepdiff. Changes: - Updated help text to show --empty-files-as-absent for grepdiff (long form only, since -E means --extended-regexp) - Updated help text for lsdiff to show -E, --empty-files-as-absent - Changed option code from 'E' to '1000 + E' to avoid conflict with the -E short option for --extended-regexp - Added case handler for long form option in grepdiff mode - Updated man page documentation for both lsdiff and grepdiff sections with clearer descriptions and examples - Documented --empty-files-as-removed as an alias (still accepted but not shown in help text) All 188 tests pass (grepdiff-status test not yet added to TESTS).

This test verifies that grepdiff -s/--status correctly shows: + for file additions (old file is /dev/null) - for file removals (new file is /dev/null) ! for file modifications (both files exist) The test also verifies that --empty-files-as-absent works correctly with -s to treat files with empty old versions as additions rather than modifications. The test currently fails - it documents the correct expected behavior that needs to be implemented. Assisted-by: Claude Code
The grepdiff -s option was incorrectly showing '!' (modification) for all matching files, regardless of whether they were additions, deletions, or modifications. The issue was that grepdiff calls display_filename() from inside do_unified() and do_context() when it finds a matching line, but the status variable was always initialized to '!' and never updated based on file existence. This fix calculates the correct status (+/-/!) inside do_unified() and do_context() just before calling display_filename(), using: - orig_file_exists/new_file_exists to check if files exist - orig_is_empty/new_is_empty to check for empty files when --empty-files-as-absent is used The fix applies to both unified and context diff formats. All 194 tests pass (188 pass + 6 expected failures). Assisted-by: Claude Code

Expanded the grepdiff-status test to cover additional code paths: 1. File deletion with --empty-files-as-absent: Tests when the new file is empty and should be treated as deleted (displays -) 2. Context diff format: Tests grepdiff -s with context diff format (*** / --- style) to verify correct status display for additions, deletions, and modifications 3. Context diff with --empty-files-as-absent: Tests empty file detection in context diff format These additional test cases ensure complete coverage of the status calculation logic in both do_unified() and do_context() functions, including the empty file handling branches. All 194 tests pass (188 pass + 6 expected failures). Assisted-by: Claude Code
